Abstract: An automobile head unit display system including an antenna, a lightbox assembly and a circuit board is described therein. The antenna is attached to the lightbox system, while the lightbox assembly is attached to the circuit board. The antenna and the lightbox assembly are in communication with the circuit board.

Abstract: A ceiling antenna housing includes a receptacle having a chamber to receive an antenna member and having a number of orifices for receiving fasteners. The fasteners each includes an aperture for engaging with hanger members typically for attaching ceiling panels to a ceiling, and for allowing the ceiling antenna housing to be easily and readily attached to the ceiling without drilling holes by the users themselves. A cover is attached to the receptacle and has a number of cavities for receiving the fasteners. The cover may also include a hooking member or an anchoring member to engage with the hanger members.

Abstract: A dielectric radiator antenna arrangement for a communication device having a ground plane is provided. The antenna arrangement may include a dielectric volume having a central axis normal to the ground plane, and mode-exciting elements. The mode-exciting elements may include a first mode-exciting element provided in or attached to the dielectric volume and extending in a plane provided at a first distance from the central axis perpendicular to the ground plane, and a second mode-exciting element provided in or attached to the dielectric volume and extending in a plane provided at a second distance from the central axis and perpendicular to both the ground plane and the plane of the first mode-exciting element. The antenna arrangement can be used for simultaneously transmitting and receiving more than one signal at one frequency with reduced coupling.
